Understanding Gestational Diabetes

What is Gestational Diabetes?

Gestational diabetes mellitus (GDM) is a type of diabetes that develops during pregnancy, typically in the second or third trimester [2]. It is becoming increasingly common among Indian women, with reported prevalence rates that vary, but are often significantly higher than in Western populations [3]. While it usually resolves after childbirth, it increases the woman’s risk of developing type 2 diabetes later in life [4].

Suppose gestational diabetes is not managed properly during pregnancy. In that case, it can pose risks for both the mother and the baby, including high birth weight (macrosomia), complications during delivery, and increased chances of type 2 diabetes later in life [2].

When Does Gestational Diabetes Occur During Pregnancy?

Gestational diabetes usually develops around the end of the second trimester [2]. It is caused by hormonal changes, such as the increase in placental hormones, that affect insulin sensitivity, resulting in high blood sugar levels. It may present symptoms like increased thirst, excessive urination, and fatigue, though it often has no noticeable symptoms and is detected only through screening tests.

Globally and in India, gestational diabetes is becoming increasingly common, affecting a larger number of women each year. While there are several reasons why women develop gestational diabetes, including genetic and lifestyle factors, dietary changes can be effective in managing the condition and ensuring a healthy pregnancy.

How Does Gestational Diabetes Affect the Baby?

When a pregnant woman has gestational diabetes, it may impact the baby in several ways.

• It increases the baby’s risk of being born larger than average, weighing 9 pounds or more. This condition, known as macrosomia, can make the delivery process more challenging and may require a C-section [5].
• There is a higher likelihood of the baby being born prematurely, which may lead to respiratory and other complications [5].
• Low blood sugar (neonatal hypoglycemia) is another potential effect on the baby immediately after birth.
• There is an elevated risk of the child developing type 2 diabetes later in life, emphasising the importance of closely managing gestational diabetes during pregnancy [2].

Regular monitoring and appropriate interventions are essential to mitigate these potential risks for both the mother and the baby.

Best Indian Foods for Gestational Diabetes Management

Despite the high prevalence of gestational diabetes among Indians, pregnant women can safeguard themselves and their babies by adhering strictly to a diabetic diet. Adherence to a balanced meal plan may prevent any adverse effects of the condition and ensure a smooth pregnancy with a healthy newborn [1].

It is strongly recommended that you consult a qualified registered dietitian (RD) or a nutritionist for an individualized meal plan. Working with a professional is the best way to manage your blood sugar levels effectively.

Here are some recommended dietary guidelines you can follow during pregnancy:

1. Carbohydrates: Focus on Quality and Quantity

For those diagnosed with gestational diabetes, paying close attention to macronutrient intake is essential, with carbohydrates taking the lead. How carbohydrates are digested and absorbed can significantly increase blood glucose levels. It is crucial to keep track of the amount and type of carbohydrate intake to prevent postprandial hyperglycaemia (high blood sugar levels after a meal) [1].

Focus on complex carbohydrates with a low glycemic index (GI).

• Fruits: Incorporating certain fruits in moderate, controlled portions like berries (strawberries, blueberries), lemon, orange, guava, and green apple into your diet can help you meet your daily recommended vitamin C intake. These fruits, particularly those higher in fiber, also provide a healthier alternative to satisfy your sweet cravings.
• Whole Grains (Brown Rice and Alternatives): Brown rice is an ideal alternative to white rice. It offers a slightly lower glycemic index and is higher in fiber, vitamins, minerals, and antioxidants [6]. Adding moderate quantities of brown rice to your lunch or dinner is wise as part of a balanced gestational diabetes diet. Other excellent whole grain choices include broken wheat (daliya) and whole-wheat flour (atta) for chapatis.
• Grains, Vegetables, and Legumes: Incorporating a variety of veggies such as beans, peas, lentils, corn, spinach, and lettuce, along with whole-grain cereals like oats, millet (ragi, jowar, bajra), barley, quinoa, and sorghum, is highly beneficial for the regulation of blood sugar levels while providing crucial nutrition to support a healthy pregnancy. These foods are packed with soluble and insoluble fibre and boast a low glycemic index, which promotes steady blood sugar release and helps prevent constipation, a common pregnancy complaint. By adding veggies, grains, and legumes to your gestational diabetes diet, you’re benefiting yourself and your growing baby.

2. Protein: Essential for Growth

A higher protein intake is needed throughout pregnancy, as it serves a crucial purpose in the development of maternal components such as the blood, uterus, and breasts, as well as the growth of the foetus and placental tissues [7].

• Dry Beans and Lentils (Dals): Incorporating red chana, rajma beans, chickpeas, and brown, green, and red lentils into your gestational diabetes diet provides essential nutrients like fibre, folate, and iron, which are beneficial for managing gestational diabetes.
• Paneer, Soy Chunks, and Tofu: Paneer and Soy are two nutrient-rich foods widely consumed. Apart from being delicious, these foods offer a host of well-documented health benefits. These are excellent sources of protein which helps slow down the absorption of carbohydrates in a meal. Soy, in particular, is rich in isoflavones, which may offer cardiovascular benefits [8].
• Eggs: Eggs are an excellent and versatile source of high-quality protein. They are naturally very low in carbohydrates and can be a great addition to your gestational diabetes diet. The egg white contains more protein, while the yolk contains healthy fats and essential micronutrients that do not significantly affect blood sugar levels. Additionally, with their low glycemic index, eggs are an excellent choice for those who want to avoid sudden blood sugar spikes.
• Fish: The nutritional value of fish and seafood is significant. These aquatic delights are teeming with protein and are incredibly lean sources of sustenance. Moreover, fatty fishes like sardines, mackerel, herring, salmon and trout are rich in DHA and EPA, a type of omega-3 fatty acid, which may enhance cognitive function and bolster brain health, especially in pregnant women [9]. Always choose low-mercury fish and cook thoroughly [10].

3. Healthy Fats: For Brain and Cell Development

It is crucial not to eliminate fats and oils from your diet, as they are necessary for your baby’s brain and central nervous system development [11]. The focus should be on choosing healthy, unsaturated fats and moderating total fat intake.

• Healthy Oils: Opt for healthy oils, including olive, peanut, and canola oil.
• Nuts and Seeds: Almonds, walnuts, peanuts, and various seeds (flaxseeds, chia seeds) are packed with vital nutrients, including proteins and healthy fats, which aid in improving heart health. For those with gestational diabetes, nuts make for an ideal snack as they have low carbohydrate content and high amounts of protein, fibre, and healthy fats, essential for maintaining a healthy diet.
• Avocado: Avocado is a delicious fruit with healthy monounsaturated fats and essential vitamins. It is low in complex carbs and has a low glycemic index. Additionally, this fruit has been found to have satiating properties, helping people feel fuller for extended periods without consuming too many calories.

Indian Foods to Limit or Avoid If You Have Gestational Diabetes

While various foods can be enjoyed in moderation, it is advisable to strictly limit or avoid sugary treats and simple carbohydrates which cause rapid blood sugar spikes.

Here are some foods and beverages you should avoid when dealing with gestational diabetes:

• Sugar-Sweetened Beverages: If you have gestational diabetes, it’s best to avoid sugar-sweetened beverages like soda, punch, and sugar-added juices. These drinks can cause a sudden spike in blood sugar levels right after consumption and offer very little nutritional value. Choose healthier alternatives such as drinking water, unsweetened tea, or plain coffee to satisfy your thirst.
• Sweets and Desserts: Like sugary drinks, it’s best to limit your intake of traditional Indian sweets (mithai), candy, ice cream, cake, doughnuts, and other baked treats. If you plan for an indulgence, it must be infrequent, small in portion size, and factored into your total carbohydrate count for the day. If you consume extra carbohydrates, engaging in low-impact activities that your healthcare provider has approved is a good idea, as physical activity helps your body process the glucose more effectively.
• Refined and Starchy Foods: Research has shown that starchy foods high in refined carbohydrates have the potential to increase blood sugar levels rapidly. These foods include white rice, white bread, potatoes (especially deep-fried or mashed), white pasta, naans, and overly ripe bananas. To maintain a healthy blood sugar level, it is recommended to monitor food intake closely. Limiting the consumption of foods with exceptionally high starch content and a higher glycemic index is advisable.
• Alcohol: Women who are pregnant need to abstain from drinking alcohol completely [10]. It is crucial for those who have been diagnosed with gestational diabetes. Even a tiny amount of alcohol can adversely affect the development of a growing fetus. It’s vital to prioritise the health and well-being of the baby and avoid any potential risks associated with alcohol consumption during pregnancy.
• Processed and Fried Food: Expectant mothers need to be mindful of their food choices and steer clear of junk food in any form. It’s best to avoid the temptation of burgers, pizzas, and pasta, as they are high in calories and barely nutritional. Additionally, frequent consumption of fried food before pregnancy is associated with a higher risk of developing GDM [12]. These foods are also loaded with unhealthy fats that can hinder healthy weight gain and blood sugar control. Instead, choose healthy and nutritious options such as eggs, fish, leafy greens, tofu, yoghurt, whole grains, and nuts to ensure a balanced and healthy diet during pregnancy.

Consult your healthcare provider or a registered dietitian to customise a diet plan according to your specific needs and preferences. They will offer personalised guidance and help you make the necessary adjustments to manage your gestational diabetes effectively.

Management of Gestational Diabetes

The management of gestational diabetes involves a comprehensive approach to ensure the well-being of both the mother and the baby. It typically includes maintaining a balanced diet, monitoring blood sugar levels regularly, engaging in physical activity, and attending regular prenatal check-ups [1].

Core Pillars of GDM Management

• Dietary Adjustments: A healthy diet focuses on whole foods, strict portion control, and avoiding sugary and processed foods.
• Physical Activity: Regular, moderate exercise helps improve insulin sensitivity and promotes overall health. The recommendation is typically at least 30 minutes of moderate-intensity exercise most days of the week, with your doctor’s approval [13].
• Blood Sugar Monitoring: Monitoring blood sugar levels helps track the effectiveness of the management plan and allows for prompt intervention if targets are not met.
• Prenatal Check-ups: Regular check-ups allow healthcare providers to assess progress, provide guidance, and make necessary adjustments to ensure the best health outcomes for the mother and the baby.

If the blood sugar levels do not stabilise 1 to 2 weeks after making the above lifestyle and dietary changes or if they are very high when diagnosed, the healthcare provider may recommend oral medications (like Metformin) or insulin injections [1]. It is common to find blood sugar levels rising as the pregnancy advances. So it is advisable to follow your doctor’s advice thoroughly.

Essential Lifestyle Tips to Manage Gestational Diabetes

Managing gestational diabetes effectively is essential for your health and your baby’s well-being. If you have been diagnosed, it is essential to know that your risk of developing type 2 diabetes later in life may be higher [4]. Regular postpartum testing and continuous follow-up with your healthcare provider are crucial.

Here are key tips to help you stay healthy and manage gestational diabetes naturally:

• Follow a Personalized, Diabetes-Friendly Diet: Create a meal plan that includes complex carbohydrates (like whole grains), high-fibre vegetables, lean proteins, and healthy fats. A well-balanced Indian diet tailored to blood sugar control is essential to avoid spikes and crashes.
• Monitor Your Blood Sugar Levels Consistently: Track your glucose levels consistently using a glucometer. Keeping a diary of your readings, meals, activities, and sleep patterns may help you identify triggers and make informed lifestyle adjustments.
• Get Regular, Moderate Exercise (Doctor Approved): Physical activity during pregnancy helps improve insulin sensitivity and keeps blood sugar levels stable. Simple exercises such as brisk walking, prenatal yoga, stationary cycling, or even dancing can be highly effective. Aim for moderate activity at least five days a week, with your doctor’s approval.
• Keep Yourself Well-Hydrated: Proper hydration is key for blood sugar regulation. Aim to drink at least 8–10 glasses of plain water daily to support kidney function and flush out excess glucose. Avoid sugary drinks.
• Prioritise Quality Sleep: Poor sleep may disrupt hormone levels and worsen insulin resistance. Establish a relaxing sleep routine. Aim for 7–8 hours of restful sleep each night to support metabolic health and emotional well-being.
• Maintain a Healthy Pregnancy Weight: Gaining the recommended amount of weight during pregnancy — and returning to a healthy weight after delivery — may significantly reduce your risk of developing type 2 diabetes later.
• Take Medications If Prescribed: Despite best efforts with diet and exercise, some women may need insulin or other medications during pregnancy to maintain optimal blood sugar levels. Never stop or start medication without your doctor’s explicit instruction.

Takeaway

The well-being of expectant mothers diagnosed with gestational diabetes depends on adopting a balanced and nutritious diet coupled with appropriate physical activity and blood sugar monitoring. Meal planning and portion control are crucial to balancing carbohydrate intake and preventing blood sugar spikes. The Indian diet offers a wide variety of whole grains, pulses, and vegetables that may help manage blood sugar levels while providing all the necessary nutrients for a healthy pregnancy.

With the proper knowledge and expert guidance, women with gestational diabetes can enjoy a balanced and fulfilling Indian gestational diabetes diet during their pregnancy. It is highly recommended to consult with a registered dietitian or healthcare provider to create an individualised meal plan that meets their specific nutritional and health needs.
